Ooh, interesting way to describe this!
I think this is pretty much what happens to me too, though I may need to think it through some more as the metaphor is new to me.
However, I got an adhd coach in November and my productivity has improved a lot since then, although I still don’t function like a neurotypical person and still have some of the problems you describe.
Ok, what helped me tons was making a weekly plan, and keeping track of how realistic it turned out to be. Actually creating the plan took several hours each week - but I gained more than that time in productivity so it was worth it, and eventually I got quicker at it, just an hour on a good week.
The weekly plan is one sheet of A4, seven columns and one block per hour for each day, though because I am usally asleep between 12 and 6 at least, i leave those hours off, and because of writing space my first and last blocks cover two hours rather than one.
I colour-code the plan. I have different colours for:
Coach/therapy/planning /self care activities;
Over time, i got better at being realistic. I learned to notice when there wasn’t enough free time, and that the amount of study time was way too little, no wonder I was behind!
I tried to make blocks of work and study on different days from each other, and I learned to recognise when things were a non-starter, like thinking I could get any ‘real’ work done on a day I had therapy. So those were the ideal days to do my planning.
I learned to say no/not now but next week/yes but in a different way that costs me less time, in response to other people’s requests for help. Before The Plan I always said yes, because I had no idea what I would otherwise be doing and realiatically I would probably just be procrastinating anyway, so I might as well be helping someone else.
Also, i learned that if I didn’t do what I had planned, I could reschedule that thing. Which helped me to see which tasks I was really procrastinating on big time, because they kept reappearing on the weekly plan! Eventually I did some of those jobs too, and there are only two or three still outstanding. I know I will get there with those too. I have learned to trust myself more that I really can finish a task. If i can’t yet, it probably means I need to break it down into smaller tasks,or get over whatever emotional blockage I have on it.
My life is not perfect since The Plan and I am actually not making one at the moment because I can just about manage to ‘see the coloured blocks’ in my head and more or less keep up with my weekly stuff, and have agreed with my coach that this is a good time to bite the bullet and create a long term plan. That’s a different story and I am not there yet.
I hope there is something in here that might help!
